In the Chingleput Diocese, this church holds the distinction of being the only one named after St. Stephen, a Deacon, and the first Christian martyr of the Church. He was stoned to death in the first century, as recorded in Acts 7.
Rev. Fr. Selvam Bellarmin was appointed as its first parish priest. Following Rev. Fr. N.R. Charles's tenure as parish priest, Rev. Fr. Terry Stephen assumed the role, taking over the responsibilities after Rev. Fr. Charles's unfortunate passing.
In May 2021, Rev. Fr. G. Prabhudoss assumed the role of Parish priest. With the support of the Parish council and parishioners, he spearheaded a substantial interior renovation of the church. The church was granted permission for the renovation by Rev. Dr. A. Neethinathan, Bishop of Chingleput, who gave his blessings for the endeavor. The consecration took place on September 23, 2021, with the blessings of Very Rev. Fr. Arul Raj, former Vicar General, Diocese of Chingleput.

This parish consists of 350 families and is served by a parish council association and several ministries. These ministries cater to the needs of both parishioners and the wider community, offering religious education programs for children, youth groups, and other activities aimed at fostering spiritual growth and community engagement.
